+Subject: [PATCH] Fix #152 crash on Apple M1 by casting 0 to (OBJECT *)
+ explicitly.
+
+Currently, when the NULL-terminated variadic function call_rule()
+is invoked, the value "0" is passed as the last argument to act
+as a terminator. However, this is an integer value, which is
+incompatible with the pointer data type expected by call_rule().
+
+This is undefined behavior in C, correct operation is not
+guaranteed. In fact, it causes b2 to crash on Apple M1 when GCC
+is used - the loop is not terminated when it should, instead, it
+keeps running, creating the following error:
+
+> lol_add failed due to reached limit of 19 elements
+
+In some cases, it can even corrupt the internal state of the program,
+creating an infinite loop.
+
+This commit fixes the problem by explicitly casting the value 0 to
+the correct pointer type (OBJECT *).
